How to Install Roof Hooks for Worcester Bosch FKT-1S Solar Panels

Measure the approximate distance of your two roof hooks for the upper rail, and make a chalk mark on the roof at each approximate location of the hooks you plan to install. For portrait-style solar panels, roof hooks will be spread apart by a distance of 24 to 40.55 inches, in pairs spaced 6.69 to 21.25 inches apart. For landscape-style solar panels, roof hooks are spaced apart by 59.84 to 76.77 inches, in pairs spaced 6.69 to 21.25 inches apart. The acceptable distance between upper hooks and lower hooks for portrait-style panels is 51.57 inches to 67.71 inches, and 23.62 inches to 32.28 inches for landscape-style panels.

Remove the hook from the package. Loosen the hexagonal nut at the back of the hook with the Allen key, then unfold the hook into a U shape.

Gently push up on the roof tile above the roof batten where you plan to install the hook. Slide up the roof tile.

Place the roof hook over the batten below. Lay the top of the roof hook in the trough of a tile.

Reposition the lower part of the roof hook so that it is tight against the batten.

Tighten the hexagonal nut with the Allen key.

Slide the tile back into place.

Repeat Steps 2 through 6 for the other roof hook in the pair. Check the distance between the two roof hooks to ensure that they are spaced within an acceptable range. Repeat this process for the hooks on the lower rail.
